Pumped water circulation... surface disturbance is unfavourable to blue-green algae growth... some limited oxygenation

The SolarBee is a floating solar-powered reservoir circulator. Depending on model the SolarBee is 10-17 feet in diameter and the flow rate is 1,250-10,000 gallons per minute. The SolarBee creates a 4-6 foot diameter column of rising water below the machine and spreads this water gently across the top of the reservoir in a long distance flow pattern. While most mixers and aerators can influence only 0.5 surface acres, SolarBees can impact up to 45 surface acres per machine. The SolarBee's mixing action has many positive effects on the water quality in lakes, wastewater ponds, and potable water reservoirs.
